The sky over New York City was a surreal, foggy orange. Though it sounds like the start of a sci-fi movie, it’s not. It was June 2023, and the discolored sky was the result of wildfire smoke from eastern Canada, which had coated the sky like a heavy wool blanket. States as far as South Carolina were issued air quality alerts. That’s just one example of one too many extreme weather patterns resulting from climate change.
“Not only is climate change an environmental issue, it’s a serious threat to public health,” said Dr. Susan Pacheco, founder of The Alliance of Health Professionals Against Climate Change.
These extreme weather events worsen airborne pollution—and higher concentrations of substances like smoke and pollen can cause or exacerbate chronic respiratory conditions like asthma and severe allergies. When outdoor air pollution then infiltrates our indoor spaces (through openings in walls, floors and ceilings) where we spend roughly 90% of our time, we face a situation where indoor air pollutants can be two to five times higher than outdoor levels. The U.S. Environmental Protection Agency (EPA), American Lung Association, and World Health Organization all view indoor air pollution as one of the greatest threats to human health.
According to the Asthma and Allergy Foundation of America (AAFA), more than 50 million Americans experience various types of allergies each year, and 25 million have asthma. As a result, indoor air quality has significant impacts on schools and workplaces: Asthma is the leading chronic cause of school absenteeism among children, and the U.S. Department of Labor’s Occupational Safety and Health Association (OSHA) estimates that poor air quality creates a combined loss of $15 billion annually for businesses due to worker inefficiency and sick days.
There is some good news, however. Facility managers can have an impact on the choices they make, helping to protect against exposure to irritants.
A key intervention recommended by AAFA is to reduce exposure to allergens by using products that are CERTIFIED asthma & allergy friendly®. This independent, physician-led certification by Allergy Standards Ltd sets strict standards for a variety of products and certifies those that are scientifically proven to reduce asthma and allergy triggers in indoor environments.
Another important way we can improve indoor air quality is to replace surfaces that harbor dust mites and other allergens. For floor coverings, there are many sustainable options available that have obtained the aforementioned certification, including sheet vinyl, LVT, and even a hybrid carpet. Area rugs should be wool or synthetic rug fibers (nylon or polypropylene); shaggy or high-pile designs should be avoided.
While it’s important to think “easy-to-clean,” also keep in mind the ingredients that were used during manufacturing. Carefully choose suppliers that transparently share the ingredients in their products, as well as the impact those ingredients have on human and environmental health. As an example, 94% of Tarkett’s raw materials have been third-party assessed down to 100 parts per million for their health impacts. Documentation like Material Health Statements and additional certifications such as Cradle to Cradle will help provide confidence in your selections.
No one needs to tell you the importance of cleaning and regular maintenance. But did you know the following were considered common sources of indoor air pollution?
• Chemical cleaners and air freshening sprays
A 2015 Harvard study found that occupants in buildings with low-VOC levels scored 61% higher on a critical thinking skills test than occupants in buildings with typical VOC levels. The score increased to 101% higher in buildings with increased ventilation rates. Another Harvard study from 2021 found that low air quality in offices can significantly impact employees’ focus, response times, and productivity. So, when choosing products—whether for cleaning, refreshing paint, or pest control—look at labels and choose low- to no-VOC options. If you need some guidance, Safer Choice is an EPA program that helps consumers and businesses find products that perform and contain ingredients that are safer for human health and the environment.
HVAC system maintenance is also critical for allergen filtration. A good rule of thumb is to have it checked at least twice a year. Your HVAC company will not only change the filters, but will also inspect and clean the ductwork, check airflow, and inspect for signs of mold. They will also keep you informed on the efficiency of your unit. Also look into adding dehumidifiers and air purifiers.
When we choose products that promote healthy indoor air quality, we can support better health outcomes and quality of life for all.
